Section 8

Electrical System and Components

Ignition Module Resistance Table 4) Position a 0.30 mm (0.012 in.) feeler

gauge between the magnet and all three

legs of the module. The ignition module

air gap is critical to proper system

performance. Do not attempt to set it

with a business card or folded

microfiche card, use the feeler gauge

specified.

5) Loosen the mounting screws, allow the

magnet to pull the module down

against the feeler gauge, and retighten

the mounting screws.

6) Rotate the flywheel to remove the feeler

gauge, position the magnet back under

the module, and recheck that the

specified gap, minimum of 0.28 mm

(0.011 in.) exists under each leg of the

module. When you are certain the gap is

correct, torque the module mounting

screws to 4.0 N·m (35 in. lb.). On a

twin cylinder engine, repeat these 6

steps to set the opposite side ignition

module.

6. Reattach the lead wires to the ignition module(s),

noting if resistance is felt, indicating a snug fit

between the male and female terminals. If any

connections do not feel snug, disconnect the lead,

lightly pinch the female terminal with a pliers, and

recheck the fit.

7. When the integrity of all connections has been

verified, repeat the spark test (Test 2).

a. If a strong, steady spark is now present

(both sides on a twin), your problem should

be corrected. Go to step 4 of Test 5.

b. If there is still a spark problem, perform all

of Test 5.

Test 5. Test the SAM.

1. Trace the red power source lead from the SAM to

the harness connection. Separate the connector and

connect the red lead of a DC voltmeter to the

harness terminal. Trace the ground lead from the

SAM (black on singles, green on twins) to the

grounding screw. Connect the black voltmeter lead

to the eyelet terminal of the ground lead or the

ground screw/bolt. Check the voltage with the key

switch in both the “START” and “RUN” positions.

A minimum of 7.25 volts must be present.

5. Check and/or adjust the ignition module air

gap(s). An air gap of 0.28/0.33 mm

(0.011/0.013 in.) must be maintained under all

three legs of the ignition module(s). Checking/

adjusting should be performed with the parts

at room temperature.

a. If the module was not loosened or

replaced, check that the specified air gap is

present under all three legs. If the gap is

correct, reinstall the second mounting

screw removed earlier and recheck gap

after tightening.

b. If the gap is incorrect, or the module was

loosened or replaced, adjust the gap as

follows:

1) Turn the flywheel magnet away from

the module position.

2) Attach the module to the mounting

legs, pull it away from the flywheel,

and snug the screws to hold it

temporarily.

3) Rotate the flywheel so the magnet is

centered under the module.
